SPECIFICATION-forming part of Letters Patent No. 607,437, dated July 19, 1898.

Application filed July 20, 1897- Serial No. 645,222. (No model.)

To all whom t may concern.-

Be it known that I, LOUIS J. HIRT, residing in Brookline, in the county of Norfolk and State of Massachusetts, have invented an lmprovement in Ooking-0vens, of Which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to coke-ovens, and has for its object to improve the construction of the same, whereby an oven of minimum size and maximum efficiency maybe obtained.

In accordance With this invention the oven is provided With a series of substantially horizontal flues arranged one above the other on opposite sides of the retort containing the coal to be coked and communicating With vertical end iiues, which are connected by horizontal lues extended beneath the bottom or sole of the retort toward the center of the oven and communicating With regenerating-chambers, as Will be described.

Figure l represents in section a cokingoven embodying this invention, the section being taken on the line l 1, Fig. 2; Fig. 2, a sectional view of the oven shown in Fig. l, taken on the line 2 2, Fig. l; Fig. 3, a section on the line 3 3, Fig. l; and Fig. 4 a detail to show the manner of reversing the course of the ignited gas and air.

Referring to the drawings, A represents a retort in which the coal to be coked is placed and Which is provided With a feed-opening a and With the usual outlets (not herein shown) for the products of distillation.

The retort A, in accordance With this invention, is heated by products of combustion created by'burning gas supplied to vertical lues a a2, Wider than the said retort and communicating With a series of horizontal lues a5 a4, arranged one above the other on opposite sides of the retort A and extended the length of the said retort. The vertical end tlues a a2 communicate at'their bottom With horizontal Ilues co5 a6, extended from substantially the transverse center ofthe vertical end iiues beneath the sole or bottom a7 of the retort and toward the longitudinal center of the said retort, Where they are connected by passages a8 a9 (see dotted lines, Fig. l) to regenerators o b of any suitable or desired construction. The gas for generating the heat is supplied to the iiues a' a2, as herein shown, by pipes b2 b3, connected with supply-pipes b4 b5 and provided With valves h6 117 and having their outlet ends extended through the Walls of the oven into the iiues a a2 at their bottom. The air to support combustion is admitted first through one regenerator and then through the other from a common supply-pipe d, connected to both regenerators b b and provided with a valve CZ", (see Fig. 4,) Which connects the air-pipe first With one regenerator, as b, and then with the other, b', and which at the same time connects first one regenerator, as ZJ, and the other, b', With a passage cl2, leading to the chimney or stack. (Not herein shown.) The manner of reversing the air and gas currents shown in Fig. 4t is old and forms no part of my present invention.

In operation gas is admitted into one of the vertical flues, as a2, Where it meets the heated air from the regenerator h and ignites and then passes through the horizontal tlues a3 a4 in contact with the sides of the retort A, throughout the length of the same to the vertical flue a', from Which it passes beneath the sole of the retort, through the flue a5, to the regenerator b, from which it-passes to the passage dleading to the chimney. After running the burning gas in the direction described for a predetermined length of time-say one hourthe course of the burning gas is reversed by closing the cock or valve 137 in the pipe b3 and opening the cock or valve bf in the pipe b2, and at the same time the valve CZ', controlling the regenerators, is reversed, so as to connect the air-supply pipe CZ With the regenerator b and to connect the regenerator b with the chimney. The air is admitted into the regenerator b and an outlet is aorded for the regeneratorb', the burning gases in this case passing up the vertical iue a', through the horizontal iiues a3 a4, down the vertical tlue a2, into the flue a6 beneath vthe sole of the retort and out through the regenerator b.

From the above description it will be seen that the retort A is heated on both sides, under its bottom, and at its opposite ends, and that the products of combustion travel the entire length of the retort in one continuous course, and .bythe construction of cokingoven herein shown I obtain the advantage of IOO the horizontal tlues for the better distribution of the heat around the retort and the advantage of the reversal of the heat by means of the vertical ues Connected to the regenerators through the fiue beneath the sole of the retort, so that a maximum coking effect may be obtained with an oven of minimum size and with a minimum amount of fuel.

In practice a series of the ovens will be included in one structure, and the end walls of the ovens may be provided with sight-openings d20. (Indicated by dotted lines.)

I claim- 1. A eoking-oven comprising a retort, a series of substantially horizontal fines arranged one above the other on opposite sides of the retort and extended substantially the length of the retort to form a continuous passage for the heat from end to end of the retort, vertical fines communicating with said horizontal fines at the opposite ends of the saine, regenerators located below the retort near its longitudinal center, and substantially horizontal Iiues beneath the sole of the retort and connecting said end lines with said regenerators, substantially as described.

2. A ooking-oven comprising a retort, a series of substantially horizontal lues arranged one above the other on opposite sides of the retort and extended substantially the length of the retort to form a continuous passage for the heat from end to end of the retort, vertical tlues Communicating with said horizontal fines at the opposite ends of the same, substantially horizontal flues communicating with the end ilues and extended below the sole of the retort toward its center, and regenerators connected to said soleheating lues, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
